OTK Engine Mount Clamp 1 Screw 92x30mm

The OTK Engine Mount Clamp 1 Screw 92x30mm (part number 0039.AA30A) is a genuine OTK billet aluminium engine mount clamp designed for OTK Senior kart chassis with 30mm main tubes. The clamp wraps around the chassis tube and is tightened with a single screw to secure the engine mount plate in position. This is the billet-type clamp, which provides a more rigid and precise clamping action compared to earlier pressed versions. Two clamps are required per engine mount installation.

Engine mount clamps must match both the chassis tube diameter and the rail spacing of your specific chassis. On OTK chassis, the standard rail spacing is 92mm centre-to-centre. The clamp tube diameter (30mm in this case) must match the outer diameter of your chassis engine bay tubes. Using an incorrectly sized clamp risks the engine mount shifting under load, which can cause chain misalignment, increased wear and potential mechanical failure during a session.
